DUST SEPARATOR AN D COLLECTOR.

Application filed Kay 24,

This invention relates to the class of gas separators and pertains particularly to a separator designed to remove dust and dirt from air.

The primary object of the present invention is to provide, in a manner as hereinafter set forth, a dust separator of improved construction capable of handling a large quantity of air and of separating dust and other solid particles therefrom with the use of a relatively low air pressure for driving the air into the separator.

Another object of-the invention is to rovide, in a manner as hereinafter set fort a dust Collector of such construction as to offer a minimum amount of back pressure with a maximum of dust separating efiiciency.

A still further object of the invention is to provide a structure of the character above set forth which is of strong and durable and simple construction, and comparatively inexpensive to manufacture and set up.

Numerous other objects and advantages of the present invention will become apparent as the description of the same proceeds and the invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawing forming a part of this specification, with the understanding, however, that the invention is not confined to any strict conforinity with the showing of the drawing but may be changed or modified so long as such changes or modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings: a

Figure 1 shows the structure embodying this invention in side elevation.

Figure 2 is a central longitudinal section of the structure.

Figure 3 is a central longitudinal section taken at right angles to the section shown in Fi ure 2.

igure 4 is a top plan view of the separator structure, and

Figure 5 is a section taken transversely of Figure 3 on the line 5-5.

Referring now to the drawings in detail;

wherein like numerals of reference indicate corresponding parts throughout the several views, the numeral 1 indicates the body of the structure which, as shown, is of cylindrical construction and is adapted or intended to be mounted in vertical positionas shown. The

sociation with the collar 5, the legs 6, the

upper ends of which extend into and are so cured to the collar as shown.

Surrounding the legs 6 adjacent the lower ends thereof is a second collar or retaining band 7 which maintains the legs in s aced relation, as will be readily understoo While applicant has shown and described a particular means for a dust separator structure in the proper upright position, it is to be understood that he does not wish to limit himself to the em loyment of such a supporting structure ibr any appropriate supporting means may be employed.

Forming the lower portion of the se arator structure is ail inverted frusto-conical body or funnel 8, the periphery of the base of which is arranged in abutting relation to the lower edge of the cylindrical body 1 while the lower constricted open end-has the longitudinally aligned discharge collar 9 opening therefrom, to which collar an appropriate lead-off pipe line may be attached as is obvious for conducting the separated dust away from the separator.

The outlet cone 8 is preferably of the same or slightly greater length than the body cylinder 1 as it has been found that this proportioning of the sections of the structure gives the best results.

Within the lower portion of the body 1 and arranged concentric therewith is an annular, body 10 in the form of a band which is of materially less diameter than the interior diameter of the body or casing 1 leaving an ,annular passageway 11 between this band shown, to secure the a slight distance inwardly of the terminal ends of the portions 15 of the arms while the upper end terminates in substantially the same plane as the upper edge of the bandilO.

The lower terminals of the arms 14 are secured to and support an upright and relatively flat cone body 17, which body has its apex in alignment with the longitudinal center of the separator structure and thus directly covers but is spaced a substantial distance from the outlet sleeve 9 of the cone body 8.

Formed in the wall of the bod 1 is an inlet opening 18 and secured to the body in -tangential relation thereto and overlying and opening thereinto through the opening 18 is the air admission pipe 19 through which air to be cleansed is conducted to the interior of the separator. As shown, the major portion of the inlet opening 18 is above the lower end of the outlet pipe 3.

In operation, the dust laden air enterin the bodyl through the tangentially arrange line 19 will. be caused to whirl about the interior of the casing setting the entire air contents of the separator in rotary motion. The

dust particles through gravitational attraction will fall through the annular passageway 11 to the cone 8 and the air will pass upwardly through the cylinder 16 and the outlet pipe 3. The cone 17 will act to direct the air in a stream through the central portion of the structure and upwardly therethrough. The separated dust will fall into the cone and be led therefrom through the sleeve 9 and an appropriate lead-off pipe or other means associated therewith.

Having thus described my invention, what i I claim is:

1. In a dust separator of the character described,-' a cylindrical upright casing, a frusto-conical head upon the upper end of said casing, an air outlet pipe opening through the central portion of said head, and terminating at its inner end adjacent the central portion of the casing, an inverted substantially frusto-conical dust discharge funnel having the base abutting the lower edge of said cylindrical casing, an outlet sleeve opening through the central portion of said inverted frusto-conical body, an annular body of materially less diameter than and concentrically arranged within said casing, means for admitting air to said casing tangentially through the wall thereof, means suspended from the lower end of said outlet pipe for setting up an upwardly directed stream or current for discharge through the outlet pipe, and a tapered guide cylinder arranged between said air directing means and the outlet pipe having the upper end of greater diameter than the lower end thereof and arranged in alignment with said outlet pipe.

. 2. In a dust separator of the character described, comprising a vertically arranged cylindrical body, a head in the upper end of said body of frusto-conical formation, a longitudinally directed centrally disposed outlet pipe extending through said head and terminating at its inner end adjacent the central portion of said body, a dust discharge funnel of inverted substantially conical form arranged beneath and opening into the easing and having an outlet at its lower central portion, an annularband of materially less diameter than and arranged concentrically within the cylindrical casing, depending supporting arms carried by said outlet pipe and extending through said annular 1 and, an upright cone body carried by the lower ends of said arms in alignment with the outlet openings, a tapered guide cylinder carried by and surrounding said arms between the first mentioned outlet pipes and said cone body, and means for admitting air to said cylinder body tangentially to the wall thereof.

3. In a dust separator, a casing having an inlet, an air outlet and a dust outlet in alignment, an outlet pipe in the casing in longitudinal alignment with the outlets, a tapered guide cylinder in spaced longitudinal alignment with the air outlet pipe, with the constricted end directed therefrom, an upright c'one body arranged in spaced aligned relation with the constricted end of the guide cylinder, and an annular band of constant diameter throughout and materially less diameter than the casing, arranged within the casin and concentric with the outlet pipe and urther being ositioned in substantially the same plane as t e larger end of the tapered guide cylinder.

In testimony whereof I afiix my signature.

THOMAS S. MONAGHAN.
